Pinout

Pin	Name	Type	Function
1	GND	power_in	Ground terminal; the datasheet rates the GND terminal current (IGND) at 800 mA absolute maximum.
2	SW1	input	Switch input that turns OUT0 and OUT1 ON together when high (VIH min 0.8·VDD, max VDD); it is pulled down by 300 kΩ and must be at or below 0.2·VDD for a low level.
3	SW2	input	Switch input that turns OUT2 and OUT3 ON together when high (VIH min 0.8·VDD, max VDD); it is pulled down by 300 kΩ and must be at or below 0.2·VDD for a low level.
4	SW3	input	Switch input that turns OUT4 and OUT5 ON together when high (VIH min 0.8·VDD, max VDD); it is pulled down by 300 kΩ and must be at or below 0.2·VDD for a low level.
5	OUT0	output	Constant current output channel 0, controlled by SW1, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
6	OUT1	output	Constant current output channel 1, controlled by SW1, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
7	OUT2	output	Constant current output channel 2, controlled by SW2, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
8	OUT3	output	Constant current output channel 3, controlled by SW2, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
9	OUT4	output	Constant current output channel 4, controlled by SW3, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
10	OUT5	output	Constant current output channel 5, controlled by SW3, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
11	OUT6	output	Constant current output channel 6, controlled by SW4, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
12	OUT7	output	Constant current output channel 7, controlled by SW4, regulating 5 mA to 100 mA with an output voltage range of 0.85 V to 19 V (absolute maximum -0.5 V to 20 V).
13	SW4	input	Switch input that turns OUT6 and OUT7 ON together when high (VIH min 0.8·VDD, max VDD); it is pulled down by 300 kΩ and must be at or below 0.2·VDD for a low level.
14	OE	input	Global PWM brightness control input that dims all active outputs; it must be connected to GND if not used, and has an internal 300 kΩ pull-up with a minimum high level of 0.8·VDD and a minimum output-enable pulse width of 1 µs.
15	R-EXT	passive	Terminal for the external resistor that programs the constant output current (e.g. 386 Ω gives IO ≈ 50 mA), to be placed as close as possible to the device and connected to GND.
16	VDD	power_in	Supply voltage terminal; the operative range is 3.0 V to 5.5 V, with an absolute maximum rating of 0 to 7 V.
17	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
